Pursuant to the new regulatory indications (chap. 8 NTC18) it is necessary to evaluate the resistant capacity of existing structures in the face of some particular situations: manifest structural deficit, change of intended use and variation of loads.
MATERIALS INSPECTION
The analysis of the mechanical characteristics of the materials constituting the supporting framework is based on the assessment of the resistant capacity of an existing structure.
PROBLEMS: concrete quality, reinforcement bars corrosion
SURVEY TECHNIQUES:
sclerometry, ultrasound, pacometry
STRUCTURAL DETAILS
In existing buildings it is of fundamental importance to be able to define the structural details to correctly analyze the mechanical behavior of the structures.
PROBLEMS: concrete quality, reinforcement bars corrosion
SURVEY TECHINIQUES
sclerometry, ultrasound, pacometry
LOAD TESTS
For existing buildings it is of fundamental utility and importance to evaluate the real behavior of the structural members through load tests.
PROBLEMS: static reliability
SURVEY TECHINQUES: static and dynamic load tests
